I thought only certain states required headrests in 68? I remeber it didn't become a 50 state requirement until 69. I had several 68 models that had no headrests whatsoever

I always prefered driving the 68's since the door opening post was in the back (where it belonged) so you could cruise with your arm out the window . They changed it in 69 since the "jersey key" (coat hanger) made them real easy to break into.
